Neptune Apex Dosing Pump-Fluid Metering System

Product Description

Connecting Power

Connect the 24V Power Source to a wall outlet and your DŌS module. It
does not need to be plugged into an Energy Bar outlet. If you choose to plug into
your Energy Bar be sure that outlet mode is set to ON.

Connecting Aquabus

Connect the 6′ aquabus cable to your DŌS module and any available aquabus
port on another Neptune Systems’ module.

Connection Success

After the initial connections have been made, the status light on the DŌS
will glow orange.

Manual Rotation

For manual rotation control of each motor there are two priming buttons
located on the center of DŌS.

Feel free to test the motors are in operating condition by pressing the
priming buttons on Pump 1 (Left) and Pump 2 (Right). The LED status light will
turn blue when the pump is running. Use these for supplementing your DOS’s
schedule with addition amounts.

Mount/ Position your DŌS

DŌS has two convenient mounting options:

Easy punch out mounting holes
on the back so that it can be mounted inside your cabinetry or wall.

Placed on a shelf or floor.
The DŌS pumps were designed offset so tubing would not kink if multiple
DŌS modules were stacked on top of each other.

Positioning Your Reservoirs And Tubing

It is of the utmost importance that your fluid reservoirs be placed below
your DŌS module. Although extremely unlikely, this could cause a gravity
siphon in certain equipment failure scenarios.

We also recommend that your DŌS tubing never be submersed in your tank.
It should be just above your water level. Again, in certain equipment failure
scenarios, this could possibly cause an unintended gravity siphon.

The DOS can pump up to 24′ vertical feet without any loss of head pressure.

PLEASE NOTE: Neptune Systems always
recommends that all equipment be mounted above the water line and/or with
appropriate drip loops!

The ins and outs of your DŌS

On your DŌS pump cover and peristaltic assembly there is an “In” and and
“Out” label. While the pump can run forward or reverse, typically it will
run “in” to “out.” So “in” will be liquid coming from a container and
“out” will be going to your aquarium.

Moving forward and in the configuration of the DŌS pumps, we will
always assume the the tubing coming from your additive container is connected
to the “in” and tubing going to your aquarium will be connected to the
“out.”

Remove the fitting from your DŌS

Remove the compression fitting from your pump cover by turning it
counter-clockwise.

DŌS Tubing and Measuring

Four meters of tubing was included with your DŌS purchase.
Now that you have a good idea of where your DŌS will be mounted we can
measure and cut the tubing to the appropriate length.

Note: Additional tubing is available.

Measure the length of tubing that will be needed to connect your
DŌS pumps from your additive container and aquarium connectors.
Then cut that tubing. A good method to securing the tubing in
your aquarium or sump is using the Neptune Systems Magnetic Probe Rack (MPR).

Attach your tubing

Place the compression fitting on your measured tubing and then
connect it to DŌS pumps.

Secure your attached tubing

Visually inspect your tubing and length as well as the compression
fitting for each tube.

Calibrating the Pump

Get two cups and fill one of them with water (tap is fine). Also have
your included graduated cylinder handy.

We will calibrate one pump at a time. Starting with the Left. Place the ‘IN’
tubing into the cup with water and then place the ‘OUT’ tubing
into the empty cup. Then follow these steps below

Priming the pump

The Display Screen will instruct you to prime the pump. Now, hold down the manual priming button on the DŌS and watch your pump start to transfer water
from one cup to to just about the end of the outbound tube. Keep at
it till liquid flows freely into your empty cup and there are no air
bubbles in the tubing line.

Prepare Calibration

We are going to prepare to calibrate the pump. Move the
‘OUT’ cup away and now place the outgoing tubing into your graduated
cylinder.

Start Calibration

On the Display Screen press ‘OK’ to start Calibrating the Pump. The pump
will run for 90 seconds attempting to dose 40 ml, then stop.

Calibration Results

After it stops, note how much water is in the graduated cylinder
after the 90 seconds and enter that value on the Display Screen.

Please note when
reading from the graduated cylinder

It’s important to view
it directly level with the liquid level- don’t view it at an angle

Note that the liquid
in the cylinder curves upward at the walls of the cylinder. The bottom is
called the “meniscus.”

Your reading is
from the meniscus and precision is important

Repeat the above steps
for the other pump.

NOTE: Neptune Systems recommends you
re-calibrate the pumps every 100 hours of operation or any time you change to a
liquid with a substantially different viscosity.
